These cars are all brought to a halt by running into a barrier supported by a set of springs. The springs are all identical and exert the same force. Rank these cars according to which stops in the greatest amount of time to least amount of time.

A. (CE)(AG)F(BDH)    B. (BF)(DG)(CH)(AE)    C. (CFG)B(DE)(AH)    D. CG(EF)(AB)DH    E. all same   


If the springs apply a constant force of 100 N (ok, so it's not a realistic spring), how long does it take H to stop?
